As part of the Council, DNREC is helping set the standards for, and launching some of the earliest versions of, open data from Delaware state agencies via the Delaware Open Data Portal.

The Open Data Council will build on, and expand, the data offerings that state agencies have long tried to provide such as DNREC’s Environmental Navigator and the FirstMAP geospatial data site for Delaware. The Council, through the Department of Technology and Information, has entered into a contract with Socrata to provide an open data portal tool that Delaware can use to publish its open data.

DNREC Data in the Open Data Portal

DNREC has added a number of datasets to the Portal and will continue to add data based on agency priorities and public requests. DNREC data in the Open Data Portal is a key part of a growing collection of data-related Environmental Perspectives stories about the work of the people of the agency.
